Over the past week, the number of coronavirus cases among foreign nationals accounted for about 16 percent of the total nationwide, and in some areas, that went up to 46 percent.
Health officials said on Tuesday that among foreigners, there are also far more cases per person.
In the week ending last Saturday, for every 100-thousand foreigners, there were 208 infections, a rate nine times higher than that of Korean citizens.
In response, the government has announced plans to encourage foreign nationals to get vaccinated.
"To increase the vaccination rate among foreigners, we will open temporary vaccination centers at industrial complexes to make on-site vaccinations available to businesses with five or more employees. Also, to make it convenient for foreigners to get their shots, we are operating a one-stop registration program."
The official noted that the Janssen vaccine, which requires only one dose, is currently available to long-term foreign residents on demand.
The authorities are urging foreigners living or working in the country to get vaccinated and to get tested if they have symptoms.
They're also asking employers to encourage vaccination among their foreign workers and to make sure they're checking PCR test results at workplace entrances.
So far, the vaccination rate among foreigners is only about half of that of Korean citizens.
As of Tuesday, a little over 24 percent of foreigners have been fully vaccinated, while for citizen's the figure is over 46 percent.
